Electrostatics Flashcards
1
Q
Coulomb’s law
A
Two point charges in free space or air exert a force on each other. The force is directly proportional to the product of the charges and inversely proportional to the square of the the distance between the charges.
2
Q
Electric field strength at a point
A
The force per unit positive charge
3
Q
Electrical field
A
A region of space in which an electrical charge experiences a force. The
direction of the electrical field at a point is the direction that a positive test charge would
move when placed at that point.
